The object is to provide a devlce for straining milk which will subj setthe latter to a plurality of strainings through sieves of differentdegrees of fineness of mesh during the process of pouring the milk fromthe original containers into shipping cans or other vessels, and tocombine such straining mediums into a single device which may be readilyhandled and applied to the necks of such cans or vessels or removedtherefrom. Another object is to provide a strainer of this characterwherein the several sieves may be readily removed from their holdingmeans for the purpose of cleansing and removing all foreignsubstancetherefrom. I a A full and complete understanding of theinvention may be obtained from a consideration of the following detaileddescription, taken in connection with the accompanying drawing formingpart'of this specification; it being understood that while the drawingshows a practical form of the inventionjthe' latter is not confined tostrict conformity therewith, but may be changed or modified, so long assuch changes or modifications mark no materialdeparture from the salientfeatures of the invention, as specifically pointed out in theappe'ndedclaims.

Fig. 4 is a side elevation of the inner removable part. I a

Fig. 5 is a plan view of the same.

-Fig. 6 is a side elevation of the outer removable part of the device;and

Fig. 7 is a plan view thereof. I Referring to the drawing, there isillustrated a metallic funnel of ordinary form, such as is 'commonlyemployed in the handling of milk, and which is adapted to fit within theneck of amilk can or other vessel for the purpose of directing orfunneling the milk into'the can. The funnel comprises the usual circularinclined wall 1 ter- 'minating at its inner or lower edge in the 'withinthe funnel at thepoint of juncture of the inclined wall 1 with reducedneck 2 and completely bridges thespace therein. This screen is adaptedto catchand to hold thelarger particles of foreign matter which the milkmay contain, and 'byi'nverting the funnel within avessel of water orother cleansing solution, may be" readily cleaned and such particlesremoved therefrom.

- At diametrically opposite points the reducedneck isprovided with aplurality of bayonet slots 5, extendingfrom the lower edge of the same,upwardly toward the screen 4, a dlstance slightly more than half itslength, the said slots terminating inoppositely disposed branches 66arranged at right angles thereto, or in a horizontal plane. These slots5, which are preferably, though not necessarily, four in number, are forthe purpose of coacting with certain means carried by removable partsofthe deyice, for the purpose of holdingithe same in position. I I

An inner, annular removable sleeve 7, havingsuitable strengthening beads8 provided at its upper and lower edges respectively and formed in amanner similarto the aforesaid bead 3, is adapted to beinwardly-directed pins 1515 which are adapted to be introduced into theother serted within the reduced neck 2, the'exterpair of bayonet slots 5formed in the neck nal diameterof the said sleeve 7 beinglsuch as toreadily permit of the introduction of the same within the bead 3 and toallow'o f" its passage upwardly 'therem, until the upper'edge of thesaid sleeve is located'ad a-' cent to the screen 4. It will be notedfrom: Fig. 1 that the said sleeve is approximately equalinlengthto.-theneck:2. The sleeve 7 is provided at a point midway of itslengthwith.an-inwardlyrdirected bead 9 extendmg entirely around the wallthereof and adapted to strengthenthesame-anditdform a rest for awsecondsieveor screen-10, which completely bridges. the'space thereimand isprefera-bly soldered or. otherwise securedt within the. said sleeve 7..v The screen 10 is thus spaced fromthexfirstnamed screen and is formedof somewhat finermesh than the latter, ,and. its 1 function is to. catchand to hold particlesof, foreign substance contained in' the milk,whichimay be smaller. in size'and whichymay have passed throughthefirstnamed screen 4.

At diametrically opposite points thesleeve 7 isprovided with a pairofoutwardly-directed pin-s 7 secured thereto in. any desired1nanner,.-at such:- a=distance from the top edge thereof as to readilyenter one orthe other of the horizontal branches 6-6of the slots 5 5depending upon the direction of turningof the inner. sleeve 7,.it being,of

course" understood,-. that the pins have been positioned within.the-upright branches of said .slots and forced-to traverse the entirelength. of the same,. asthe inner sleeve 7 is forced up: into:itsposition. within, the reduced-l neck. of the funnel.

, Anouterremovable sleevei llis adapted to. fit. over the said. reducedneck 2. of the funnel, having. at its upperedge a strengthening. bead 12whicln is located adjacent to the lowerend .of. the inclined wall 1ofthe funnel, when; theisaid sleeve is in position. thereon. The sleevelliis further provided atits .lower edge with 1 an inwardlydirectedflange 13 extending entirely around the same and adapted to strengthen.the same and to form. 3,.- seat whichis cut tQFfit .tl18 Sald'Sl8eV6aIld is sol.- d ered or. otherwisesecured within the sleeve upon.the; said. flange; Thisv screenlt is thus positionediandfheld, in spacedrelation to the intermediate screenlO, and, at a distance,therefromvsubstantially equal to the distance betweenthe first and.second named screens, and is formed'of astill finer. mesh than thesaidiinterme'diate screen, for the purpose ofl a. fi-nal effective.straining, of the milk to remove the smallest" particles; of foreignsubstance therefrom.

1 The outer removable sleevellis provided with a pair of oppositelydisposed, in-

for a. lower screen 14,--

- 2 of the funnel, and to be turned either to the right or the left toforcethe same into one of" the terminal branches 6 to lock the outersleevell in position on the neck of the funnel, attention being directedto the fact that the pins 7 and 15 of the inner and outer removablesleeves respectively are so positioned thereon as to enter the saidbranches 6, when the said sleeves. are: in their proper positions withrelation tothe neck. ofthe funnel. In practice thescreens are made ofcopper wire and are heldabout one inch apart. Itis a wellknown. fact;that sediment and. hairs become embedded in the fabric of cloth milkstrainers, making. it almostimpossible to keep them, clean; By theconstruction shown,.the strainer maybe kept in a thoroughly, sanitarycondition at all-times. v p

. From. theforegoing,.itwill be seen: that a simple,.cheapand durablestrainingdevice has been provided for use in the handling of milk orsimilar commodities, which may. be readily manufactured. andsold at alow. cost, which may be easily applied to or removed from the necks ofcans or other vessels, and. which is capable of thorough cleansing, byreason of the separable parts which. permit of. ready accessto both.sides of the several screens to remove any accumulations thereon.

What I claim is: v

l. A. strainer comprisinga body havinga neck and-a screen therefor,.a1rinner openended cylindrical. sleeve carrying a screen and adapted toslide within. said. neck and an outer open-ended. cylindrical sleevecarrying a screen. and adapted. to slide over said neck, the saidscreensbeing maintained inspaced. relation to each other. p

2. A strainer comprising a bodyhaving a cylindrical. neck, a screen forsaid. neck, an open-ended cylindrical sleeve alsoihavin-g a screen andadapted-to fit withinsaid. neck beneath the screen thereof, and having alength substantially equal thereto, and. an outer open-ended cylindricalsleeve carrying a. screen and adapted C-OJ-fill outside said. neck,.andbeing of somewhat: greater length than said neck, the screens beingmaintained in spaced relation to each other, and coa'ct ing, meansprovided. on the neck and. sleeves for maintaining them in position.

SI A strainer.comprising a funnel. having. a reduced neck at its lowerend,.-and a neck, whereby the said screens are maintained in spacedrelation to each other.

4. A strainer comprising a funnel-shaped body having a reduced neck atits smaller end, and carrying a screen at the upper portion of saidneck, said neck being provided With a plurality of diametrically opposedbayonet slots, an inner open-ended sleeve adapted to enter said neck, ascreen of finer mesh carried by the sleeve midway of its length andhaving a pair of opposite outwardly extending pins adapted to be turnedCopies of this patent into a pair of said slots, and an outer openendedsleeve adapted to fit over the reduced neck and having a screen of stillfiner mesh at the lower end of the same, said sleeve having oppositeinwardly-directed pins for engagement With another pair of said slots,the said slots and pins serving to maintain the sleeves in position Withrelation to the said neck and the several screens in spaced relation toeach other.

In testimony whereof I afiix my signature.
